Using R, I want to produce multiple character strings such as:

"modelCheck("var1_d.bug")"  
"modelCheck("var2_d.bug")"  
...  
"modelCheck("var10_d.bug")"

I would usually use a for loop and paste (if I did not have to worry about the double quotation marks) as such:

for(i in 1:10){
    str<-paste("modelCheck(var",i,"_d.bug)",sep="")
    print(str)
}

However, I need to include the double quotation marks within the character string, hence the appeal for help?

Simply escape the quotation marks with backslashes:

paste("modelCheck(var"",i,"_d.bug")",sep="")

An alternative is to use single quotes to enclose the string:

paste('modelCheck(var"',i,'_d.bug")',sep="")
